The energy level diagram shown below represents a fictional gas. What is the energy of a photon that would move an electron from
level 2 to level 5?
A. 5.8 eV
B. 4.8 eV
C. 4.2 eV
D. 2.65 eV
1 answer:
The energy of a photon that would move an electron from level 2 to level 5 : B. 4.8 eV
<h3>Further explanation</h3>
The electron energy at the nth shell can be formulated:
<h3>En = -Rh / n²
</h3>
Rh = constant 2.179.10⁻¹⁸ J
So the electron transfer energy (ΔE)
ΔE = E final- E initial
energy at n=2(level 2) = -5.3 eV
energy at n=5(level 5) = -0.5 eV
So the energy absorbed :
